Hibernate is an Object Relational Mapping (ORM) tool that implements the Java Persistence API and provides relational persistence and query service for Java and .NET. Hibernate, as a framework for mapping object-oriented domain models to relational databases, eliminates repetitive coding work and helps Java Developers reduce development time and lines of code, thereby extending ORM capabilities.

Tests: 3

I am well-versed in Software development, with knowledge and experience in Java. I have programmed various applications, and I am capable in Object Oriented Programming. I also have SQL and Database Design knowledge, having created databases in the past.
Since July 2014 I have also been studying Data Science through Coursera, edX and other platforms, and I can use R to manipulate datasets, derive conclusions and prepare machine learning algorithms. I can use various preparation (data cleaning, data selection, charts, etc), pre-processing (centering, scaling, PCA, Imputation, etc) and modeling (Inference tests, Regression, ANOVA, Classification, Random Forests, Boosting, Bootstrapping, etc) methodologies. I also know Excel (data manipulation, charts, Pivot tables, Lookup, Optimization) and VBA. Currently I am learning Android.
I have a wide range of knowledge in many fields (although I am not specialized in any of them), which allows me to utilize data more effectively than someone who has no idea how the data are related and simply tries to combine them randomly. My interests include (but are not limited to) Astronomy, Meteorology, First Aid/Medicine, Information Technology, Economics, Psychology, Artificial Intelligence and Computer Graphics.
Finally, I can work both in teams of any size, as well as alone, and carry out my tasks responsibly and in time. I am used to handling deadlines, and I have worked with many teams in various settings (corporate, army, university, etc).

My passion is Web. Doesn't matter if it's 2.0, 3.0 X.0! In today society information is everywhere and one big part is transferred over the Web using HTTP(S) protocol. Having the possibility to exchange, analyze and create new information everyday bringing value to the customers is something that keeps me in this world. Technologies are tools and in order to know which tools fits clients needs the best it's required to know and understand different approaches available to one Web Engineer.
My ticket to Web was PHP - it is a powerful tool but it requires understanding the platforms it's running on in order to avoid bottlenecks and provide customers with rich and fluid experience. For the last year and a half I had a chance to dive into the world of distributed systems using PHP, Gearman and AWS infrastructure.
Technolgies and framework I comfortable working with:
- PHP5 / CodeIgniter / Zend Framework 2 / REST
- MySQL
- Apache (mod_php and FastCGI + PHP-FPM) / Engine X (nginx)
- Gearman
- Unix servers (Ubuntu Server)
- Amazon Web Services - Mostly related to scaling
- GoogleAPI
- MongoDB
- JavaScript / AJAX / jQuery
- HTML5/CSS3
- Python / Django
Technologies and frameworks I'm currently working on:
- Java
- Spring MVC, Spring JDBC, Spring Security
- Jetty
For the end I've left some cool technologies and platform I had a chance to get in touch:
threeJS, backboneJS, Parse, Heroku, AppFog, NodeJS
